Optical endstops not triggering with Marlin 2.0.X and SKR 1.3

I'm using an SKR 1.3 with Marlin 2.0.X. I'm trying to get my optical sensors working on my Hypercube Evolution. I'm only using Min endstops.

I've connected S Pin to V pin sent a M119 and no change
I've connected S Pin to G pin sent a M119 and no change

After the test

"I've connected S Pin to V pin sent a M119 and no change
I've connected S Pin to G pin sent a M119 and no change"

There are only three possibilities left
1) you have edited the pins files and the end-stops are no longer looking at the correct pins on the board.
2) Those pins are dead.
3) not your actually using a SKR 1.3 controller, perhaps a SKR 1.4

Did you check if the actual board pins are correctly defined under pinx_"board name".h file? Check the pin layout of the board:

I had the jumper on for XST and YST. I removed them and it started working. Although now I'm using sensorless homing and not using the X and Y endstops.
